Optical Methods for Monitoring Demineralization and Caries

  • Daniel FriedEmail author


In this chapter optical methods for monitoring demineralization and remineralization on tooth coronal and root surfaces are presented. Methods discussed include transillumination and reflectance imaging with visible and near-IR light, fluorescence based imaging methods and optical coherence tomography (OCT). OCT can be used to acquire tomographic images of the structure of lesions in vivo and can be used to provide depth resolved measurements of the severity of demineralization. OCT can be used to detect if occlusal and proximal lesions have penetrated through the enamel to the underlying dentin. In addition, OCT can be used to monitor changes in lesion severity and presence of a transparent highly remineralized surface zone that is formed when lesions become arrested.
